China is a country with a large population, and due to our cooking way (we use frying most ) and population, China becomes the biggest cooking oil consumption country.And the earliest cooking crushing technology took place in East Asia, primarily in Manchuria, China, using primitive stone mills to extract soybean oil. Later the cooking oil technology appears in USA and Europe, and it develops quickly there; But in the recent 50 years, China Government encouraged the development of cooking oil technology and machines, we also established a University specialized in oil technology study and training—He Nan University of Technology.
This University located in Zhengzhou city, Henan; My company is in same city too. The university is specialized in oil technology study and development, and is the only one University in oil field in China. All our engineers are graduated from this university, and now one of our superior engineer is the Honored Professor from this university; We have the most professional engineers team, under our engineer team’s design and technology, we have helped China government to set up many big soybean, rice bran, peanut oil mills with capacity 1000-2000TPD;
Doing Group starts to expand the international market for cooking oil projects in 2011, set the first office in Xinxiang city, and along with business development, we set our second office(the head office) in Zhengzhou city(capital of Henan province) in 2013. We also have branch offices and parteners in different countries, like Mexico, Nigeria, UZ, Thailand, Vietnam, Indonesia, Malaysia etc .
With 40 years rich experience in technology design, manufacturing, installation, and debugging, technical training etc; DOING is now one of the leading companies in China.
